Budibase · @Budibase/Server · CVE-2026-100682
**Name of the Vulnerable Software and Affected Versions**
Budibase Server versions prior to 3.45.0
**Description**
An arbitrary file write issue exists in the PWA icon upload endpoint. The system extracts user-supplied ZIP archives without proper symlink validation. Users with the BUILDER role can create a malicious ZIP file containing leaf symlink entries followed by duplicate file entries to write arbitrary files as root, which can lead to remote code execution.
**Recommendations**
Update Budibase Server to version 3.45.0 or later.
